AbstractA new design evolved from the surface microdischarge electrode system has been developed for the application of surface disinfection. Having the electrode encapsulated in a dielectric surface the plasma is produced directly on the surface of the electrode which therefore becomes disinfected. Experiments with bacteria were carried out and results show that the surface can be disinfected within 30 s with typical operating conditions. Even sterilization appears possible in a reasonable time. Possible applications of this electrode design are discussed for regular disinfection of work surfaces, laboratory benches, etc.magnified image
